  1. NICI Management CDR Presentation

  2. AO Procurement • Status of MOU • Has been reviewed and agreed upon • IFA director has agreed to support the project • MOU is going through approval and signature process

  3. AO Procurement Schedule Delivery of APDs(MKIR Purchased) to IFA As soon as received(Sept 02) Lab testing of all components using UH lab optics Nov. 2002 to June 2003 Delivery of NICI Optical bench and optics to IFA May 2003 Testing of components in NICI bench – May 2003 May 2003 to June 2003 Delivery of tested working system to MKIR(Hilo) End of August 2003

  4. AO Procurement Avalanche Photodiodes (APD) Apds have been ordered Expected delivery is much improved at Sept. 2002 Price is as expected

  5. AO Procurement IFA Component Tests DM stroke and curvature measurement DM flatness DM influence functions(4 voltages over full range) Membrane mirror defocus distances Membrane mirror resonant frequency Lenslet throughput measurement@632 nm

  6. AO Procurement IFA Payment Milestone Schedule 20 % at completion of Start of Work 20% upon completion of the DM construction 30 % upon successful lab tests 30 % upon completion and acceptance

  7. Optics Procurement • Optical Fab drawings are complete • Key Vendors have been selected • SSG Inc for OAPs • ISP for spheres and flats • Requirements trades-offs made • Orders will be ready to place after CDR

  8. Tracking and Controlling Changes to Drawings • Changes are made only two ways • Revision to original print by Mechanical Engineer that is reissued to machine shop via electronic PDF file • Marked up print at machine shop or assembly lab indicating small change made • Marked up drawings are then sent to ME in batches to update the model

  9. Tracking Fabrication of Parts • Parts are sent for fabrication in work packages that correspond to parts need for each integration step. Often a few work packages will make up the parts needed for each integration step. • There is a master list of parts for each step • As parts are received they are cleaned, bagged, labeled and checked off on the master list

  10. Tracking Fabrication of Parts • For items with long construction times progress will be monitored by asking for periodic updates from the vendor. This would typically be done 1time/month for major items such as optics and machine shop parts. • Some items such as the vacuum jacket or optics will require in-person visits it ensure that quality and schedule goals will be met

  11. Parts Testing • Keys to getting accurate parts • Careful vendor selection • Detailed vendor documentation • Inspection when possible • Subassembly parts inspected at first “dirty” assembly shortly after received • Optics accuracy relies on vendor documentation

  12. Parts Storage • Machine shop parts are cleaned, bagged and labeled by part number and stored in cabinets by subassembly • Purchased parts will stored with the machine shop parts by subassembly • Off the shelf equipment items will have a NICI sticker attached and given an inventory number

  13. Subsystem Assembly and Testing • Structures • Alignment measured as assembled • Mechanisms • Tested “dirty” and fitted • After fitting they are painted and polished • Cold testing upon integration • Optical checks to verify proper function

  14. Integration Phase Resources • Electronics will be built, integrated and tested at the MKIR office in Honolulu and shipped to Hilo once complete. • Peter Onaka • Jim Hinds • Technician

  15. Integration Phase Resources • Mechanical and optical structures will be integrated and tested at the MKIR office in Hilo • Doug Toomey • Dayton Jackson Machine Works • Technician • MKIR Engineer • Jim Hinds

  16. Cash Flow • The NICI payment plans as designed to provide a starting surplus of $200K that would build to $500K after the CDR. The Surplus would remain at $500K until the integration phase. • In reality this amount varies over the three month payment interval

  17. Safety ReviewDetailed documentation in SDN1013 NICI Safety Issues NICI Safety Policy Safety has utmost priority in the design and operation of NICI. All staff involved in the NICI design and construction must place the highest priority on the safety of those that will use NICI. If at any time there is the possibility of risk to safety it should be brought immediately to the attention of the Project Manager. NICI must comply with all relevant notified Site Safety Requirements applicable to Mauna Kea and Cerro Pachon and conform to good, safe engineering practices

  18. Safety ReviewDetailed documentation in SDN1013 NICI Safety Issues Applicable Safety Documents Gemini Project Safety Program PG-PM-G00009 Gemini Instrument Site Safety Policy for Mauna Kea & Cerro Pachon OSHA Regs PART 1910 Subpart F, 1910.66 to 68 Subpart G 1910.94 to 98 Subpart M 1910.166 to 169 Subpart S, 1910.301 to 399 Applicable Gemini Instrument Documents ICD 1.1.13/1.9 Interlock System to Science Instruments ICD 1.9/2,7 Science Instruments to Facility Handling Equipment ICD 1.9/3.6 Science Instruments to System Services ICD ICD 1.9/2.7 Science Instruments to Thermal Enclosures ICD-G0013 Gemini Environmental Requirements ICD-G0015 Gemini Facility Handling Equipment and Procedures

  19. Safety ReviewDetailed documentation in SDN1013 NICI Safety Issues Recommended Training General Awareness Hazardous Material Training Specific Hazardous Material training in Liquid Cryogens Specific Hazardous Material training in Compressed Gases Transportation of Compressed Gas NICI Safety Officers Until Final Acceptance Douglas Toomey will be the NICI Safety Officer. After acceptance IGPO will appoint a successor safety officer.

  20. Mechanical Safety Design RequirementsSummary Structural Integrity - factor of 2 safety factor including slews and rotations, TIG welding Fasteners - factor of two safety factor Materials - alloys and tempering called out, material reports requested from vendor Coatings – specify coatings to minimize corrosion Lifting points – design each lifting eye can support the full weight of NICI Mass and center of gravity – must be maintained Sharp edges – design to minimized Mechanisms – design to avoid pinch hazard Compressed gas – spec properly rated fittings Electronic shock – specify warming labels and interlocks on high voltage Cabling – specify properly rated components and avoid loose cables Overcurrent protection – Equipment must have overcurrent protection and/or breaker Interlock protection – Interlock switch must be supplied to lock out mechanism moves Grounding – Must be specified and provide safety grounding of cabinets Component rating – Whenever possible components must be rated for MK Static – Grounding points for straps must be furnished

  21. Specific Safety Warnings Review of Manuals Electrical shock hazard High current on APDs Sweeping when Rotating Tipping hazard Cryogen handling Nitrogen suffocation hazard Disconnecting Cold Head Ice plug in precharge neck Compressed gas Compressed GasTransportation NICI Handling braces Falling Tool Hazard Cabling

  22. Areas of Risk to the Instrument • Vacuum leaks • Optical Surfaces • APDs • Static Discharge
